Title: Rotor for brushless dc motor
Inventor: CHEONG SUNG GYU
IPC: H02K1/27
Filed: 1998-12-31
Abstract: PURPOSE: A rotor of brushless DC motor used by a washing machine is provided to reduce the vibration and noise by decreasing the density of magnetic flux at the boundary point of the rotor pole. CONSTITUTION: An edge(11) is cut off of the rotor toward the shaft direction, which cut dimension is within 2.5-25 electrical angle so air gap of the cut area is increased. According the big air gap, the reluctance is increased and the density of the magnetic flux is decreased when magnetizing the permanent magnet of the yoke. Then the vibration and noise caused by the cogging torque are reduced. When driving the motor with weak magnetic field, the current for spin dry is reduced because of improved torque and acceleration caused by reduced reverse electromotive force in the operation region of the weak magnetic field.

Abstract: PURPOSE: A multi-level sense amplifier of a flash memory is provided to reduce a data read sensing error by maintaining the same offset in a program and read operation by a sense amplifier. CONSTITUTION: A main cell sense amplifier(400) performs a data read operation or a program operation in the same path. a bias switching unit(700) switches so that the read operation or the program operation of the main cell sense amplifier(400) can be done in the same path. A program reference cell sense amplifier(600) generates a reference voltage by means of an external reference voltage and stores it, and outputs the reference voltage by a program reference cell word line signal. A read reference cell sense amplifier(500) stores the output signal of the program reference cell sense amplifier(600) as a read reference data by a reference cell word line signal.
